• What is the cause and solution for SAP error message WG057 - Supplying plant & cannot be the same as the ordering store ?

  Certainly! Here's a detailed explanation for the SAP error message WG057: "Supplying plant & cannot be the same as the ordering store":
  
  Error Message:
  WG057: Supplying plant & cannot be the same as the ordering store
  
  Cause:
  This error occurs in SAP Retail when you try to create or process a stock transport order or a goods movement where the supplying plant (the plant that supplies the goods) and the ordering store (the receiving location or store) are the same. 
  In SAP Retail, the system expects that the supplying plant and the ordering store are different entities because a store cannot supply itself. This is a business rule to prevent illogical or redundant stock movements.
  
  When does it occur?
  
  During creation or processing of stock transport orders (STO) between plants and stores.
  When setting up or posting goods movements in Retail Logistics.
  When the system checks the relationship between supplying plant and ordering store in the order or delivery document.
  
  
  Solution:
  
  
  Check the master data:
  
  Verify the supplying plant assigned in the stock transport order or goods movement.
  Verify the ordering store (receiving location) in the document.
  Ensure that the supplying plant and ordering store are different.
  
  
  
  Correct the document:
  
  If you mistakenly entered the same plant/store in both fields, correct the ordering store or supplying plant to a valid different entity.
  
  
  
  Review configuration:
  
  Check the configuration of plants and stores in the system.
  Ensure that the plant assigned as supplying plant is not the same as the store assigned as ordering store.
  In SAP Retail, stores are often assigned to plants or have their own plant codes; make sure these are correctly maintained.
  
  
  
  Business process check:
  
  Confirm that the business process requires a stock transfer between two different locations.
  If the intention is to move stock within the same store or plant, use appropriate internal movement transactions instead of stock transport orders.
